Powershell Timeout From C#

Question

I want to set a timeout on powershell scripts I have running in c#.

My code to run my scripts is

  private void RunPowerShell(string scriptText)
        {
            string tempFile = Path.Combine(Environment.ExpandEnvironmentVariables("%temp%"), "PinScript.ps1");
            var file = new StreamWriter(tempFile);
            file.AutoFlush = true;
            file.WriteLine(scriptText);
            file.Dispose();

            string output, errors = string.Empty;
            //this is basically a helper method that runs an exe via the command prompt in c#
            //I want to keep this as is and either add an argument to powershell.exe or alter the 
            //.psi scripts themselves
            _cmd.Run(@"powershell.exe",
                            @"-NoProfile -ExecutionPolicy Bypass " + @"& '" + tempFile + "'",
                            out output,
                            out errors);

            Console.WriteLine("Powershell Output: " + output);
            Console.WriteLine("Powershell Errors: " + errors);
            File.Delete(tempFile);
        }

I see there is code that works to time out a script here but I cannot understand how to ingrate that concept into what I have above.
